The technique adopted is to mix quantities of mica flakes and granular bentonite into special batches of mud which is pumped down the hole. The drill pipe is then withdrawn and the hole left undisturbed for a time being. Mica flakes tends to plate out on the walls at the lost zones and reduce the size of the holes through which the mud can pass. After a short interval, the plug is strong enough to permit circulation to resume without loss. Drilling then proceeds normally until a depth well below the lost circulation zone.

Mica sheets are available in different sizes and temperature. There are many uses for Micanite sheets, such as, heat barriers and fabrication of different components as per customer specifications and requirements. These sheets can withstand temperatures ranging up to 900 degrees Celsius.

Mica Disc provides the best protection to circular viewport glasses and perfect visibility for checking the degree of combustion and liquid level in high pressure steam boilers. It is also used in breathing apparatus, communication devices, fuses, geiger counters, broadband waveplates for optical instruments, etc.

Cut mica plates are specially made of superior quality muscovite ruby clear mica films, split and gauged to a specified range of thickness varying between 20 to 100 microns into a close controllable tolerance within a micron, suitable for use in the manufacture of silvered mica plates and mica capacitors. Plain smooth surface, clean punched sharp edges, uniform thickness, free from metallic stains, spots, finger prints, scratches, cracks, tears, pin-holes, stones, buckles, ridges, etc., are some of the important points observed while manufacturing cut mica plates. They are manufactured as per ASTM Specifications: D748-71, possessing electrical, physical and visual quality requirements as specified in the following table.

All cut mica plates are electrically tested by means of a high frequency spark for conducting particles and pinholes. They are then metallised with a silver paste by a screen printing method to form a thin electrodes-less than 3 mm. Silver paste is printed onto the mica in different patterns as per required specification. The actual silver metallisation is done within a range of 5 to 8 microns on both sides.The deposited layer of silver is controlled to achieve its required capacitance. Glass is used as the fusing agent. The metallising bond which unites these two elements permits diffusion of heat over a wider surface. While the points of calorofic transfer are increased, the thermic resistance does not influence the insulation of the unmetallised area of the film.
